Understanding Adenoma Detection Rate (ADR)
The Adenoma Detection Rate (ADR) is a crucial quality indicator in colonoscopy procedures. It measures the percentage of screening colonoscopies where at least one adenoma (a precancerous polyp) is found. A higher ADR generally signifies a more thorough and effective colonoscopy examination, as it suggests the endoscopist is more skilled at identifying and visualizing these important lesions.
Improving ADR is a key goal for gastroenterologists and healthcare institutions aiming to reduce colorectal cancer incidence and mortality. Factors influencing ADR include patient preparation, withdrawal time, the endoscopist's experience, visualization techniques, and the use of advanced imaging modalities.
This calculator helps you determine the Adenoma Detection Rate based on the number of screening colonoscopies performed and the number where at least one adenoma was detected.
